Can a person be assured of salvation? Can genuine believers be lost? Is our salvation totally in the hands of Christ, and therefore secure? Or is it partly in our own hands, and therefore fragile and uncertain? If our salvation is secure, what is the significance of the New Testament warnings against falling away? This extensive study is in a table format, presenting New Testament passages relative to assurance along with comments on their meaning and significance. Technically this is not a series of studies, but one long and comprehensive study.
